PRINCE William shouted angrily at his father over his arguments with the tearful Princess Diana, a royal author reveals.

Prince William, the eldest son of Prince Charles and Princess Diana, was born in 1982 – the year after his parents’ royal wedding. As Diana became increasingly unhappy, the young William would witness his mother and father’s rows, which often ended in tears. Their marriage would eventually break down, and the royal couple separated in 1992 before eventually divorcing on the advice of the Queen in 1996.

Ms Nicholl writes: “He could not bear to hear his parents bicker any longer.”

She reports how the young prince shouted angrily: “I hate you, Papa. I hate you so much. Why do you make Mummy cry all the time?”

Ms Nicholl also describes how William “slammed the door” in a rage while shouting at his father.

She says that the young prince “had been aware for some time that his parents were not happy”.

The Vanity Fair writer goes on: “The princess had become increasingly dependent on her elder son, who she regularly confided in, and it was William who would pass his mother tissues through the bedroom door as she sobbed on the other side.”

She adds: “It was a heavy burden for a young boy."

Whereas his older brother reacted angrily, Prince Harry was much more sensitive and became withdrawn, she writes.

Both boys would be shielded from the breakdown of their parents’ marriage as they entered boarding school, which provided a “great sense of relief”.
